Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The method of claim 1, wherein the first HPLMN S-NSSAI is included in a requested mapped network slice selection assistance information (NSSAI) information element (IE).

3

3. The method of claim 1, wherein for the first PDU session that is associated with the first HPLMN S-NSSAI, the UE is performing mobility from N1 mode to N1 mode from another VPLMN to the VPLMN.

4

4. The method of claim 1, wherein for the first PDU session that is associated with the first HPLMN S-NSSAI, the UE is performing mobility from N1 mode to N1 mode from the HPLMN to the VPLMN.

5

5. The method of claim 1, wherein in response to the UE not having any S-NSSAI applicable in the VPLMN, a requested mapped NSSAI IE in the registration request message does not include any S-NSSAIs.

6

6. The method of claim 1, wherein in response to the UE has a second VPLMN S-NSSAI applicable in the VPLMN for a second PDU session that is associated with a second HPLMN S-NSSAI, the registration request message further includes a requested NSSAI IE that includes (1) the second VPLMN S-NSSAI applicable in the VPLMN for indicating a slice to which the UE intends to register for transferring the second PDU session, and (2) the second HPLMN S-NSSAI as a second mapped S-NSSAI corresponding to the second VPLMN S-NSSAI applicable in the VPLMN.

9

9. The apparatus of claim 8, wherein the first HPLMN S-NSSAI is included in a requested mapped network slice selection assistance information (NSSAI) information element (IE).

10

10. The apparatus of claim 8, wherein for the first PDU session that is associated with the first HPLMN S-NSSAI, the UE is performing mobility from N1 mode to N1 mode from another VPLMN to the VPLMN, or from the HPLMN to the VPLMN.

11

11. The apparatus of claim 8, wherein in response to the UE not having any S-NSSAI applicable in the VPLMN, a requested mapped NSSAI IE in the registration request message does not include any S-NSSAIs.

12

12. The apparatus of claim 8, wherein in response to the UE has a second VPLMN S-NSSAI applicable in the VPLMN for a second PDU session that is associated with a second HPLMN S-NSSAI, the registration request message further includes a requested NSSAI IE that includes (1) the second VPLMN S-NSSAI applicable in the VPLMN for indicating a slice to which the UE intends to register for transferring the second PDU session, and (2) the second HPLMN S-NSSAI as a second mapped S-NSSAI corresponding to the second VPLMN S-NSSAI applicable in the VPLMN.

15

15. The non-transitory computer-readable medium of claim 14, wherein for the first PDU session that is associated with the first HPLMN S-NSSAI, the UE is performing mobility from N1 mode to N1 mode from another VPLMN to the VPLMN, or from the HPLMN to the VPLMN.

16

16. The non-transitory computer-readable medium of claim 14, wherein in response to the UE not having any S-NSSAI applicable in the VPLMN, a requested mapped NSSAI IE in the registration request message does not include any S-NSSAIs.

17

17. The non-transitory computer-readable medium of claim 14, wherein in response to the UE has a second VPLMN S-NSSAI applicable in the VPLMN for a second PDU session that is associated with a second HPLMN S-NSSAI, the registration request message further includes a requested NSSAI IE that includes (1) the second VPLMN S-NSSAI applicable in the VPLMN for indicating a slice to which the UE intends to register for transferring the second PDU session, and (2) the second HPLMN S-NSSAI as a second mapped S-NSSAI corresponding to the second VPLMN S-NSSAI applicable in the VPLMN.
